Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

A set of essentially identical panels, such as building panels, provided with a mechanical locking system including a displaceable tongue, which is arranged in a displacement groove with a first opening at a first edge of a first panel. The displaceable tongue is configured to cooperate with a first tongue groove, with a second opening at a second edge of an adjacent second panel, for vertical locking of the first and the second edge. The height of the first opening is greater than a second height of the second opening.

A set of mutually lockable panels comprises a first panel having an edge including a male part and a second panel having an edge including a female part for receiving the male part of the first panel in unlocked condition of the panels. The male part has an outer side which, in locked condition of the panels, is directed to the second panel in a direction substantially parallel to the front face of the first panel, and an opposite inner side which is provided with a locking surface. The female part comprises a locking member, which is pivotable about a pivot axis that extends substantially parallel to the edge of the second panel and an actuator for rotating the locking member from its unlocked condition to a locked condition of the panels.

A set of floor panels for forming a floor covering, which comprises at least two floor panels, which each comprise an edge provided with a coupling part, wherein the coupling parts are configured such that they allow realizing a coupled condition between the floor panels, by means of a substantially straight-lined coupling movement of the one floor panel in respect to the other floor panel, according to a direction substantially perpendicular to an installation plane; and wherein the coupling parts are configured such that they, in the coupled condition, realize a tensioning force pressing the coupled edges towards each other.

A floor panel with a substrate, including thermoplastic material, a decor provided thereon, and, on at least one pair of opposite edges, coupling parts realized at least partially from the substrate. The coupling parts allow a mechanical locking between two of such floor panels, where the substrate includes a rigid, non-foamed substrate layer of thermoplastic material.

A floor panel with a substrate and a decoration provided thereon. The substrate includes at least a foamed layer of thermoplastic material and at least a reinforcement layer. Additionally, a method for manufacturing such floor panels with a substrate and a decoration, where the substrate includes at least a foamed layer of thermoplastic material and at least a reinforcement layer.

Floor panel, with a horizontally and vertically active locking system allowing that two of such floor panels can be connected to each other at said sides by providing one of these floor panels, by means of a downward movement, in the other floor panel; wherein the vertically active locking system comprises a locking element in the form of an insert; wherein this locking element comprises at least a pivotable lock-up body; characterized in that the pivotable lock-up body comprises a support portion which is rotatable against a support surface pertaining to the floor panel concerned, and more particularly in a seat.

A floor panel has a substrate and a decorative layer of wood veneer provided thereon having a thickness of 1 millimeter or less. The substrate has an average density of more than 750 kilograms per cubic meter. The floor panel is rectangular and oblong and comprises a pair of opposite short edges and a pair of opposite long edges. The floor panel, on at least said two opposite long edges, is provided with coupling means allowing that two of such floor panels can be coupled to each other in a vertical direction perpendicular to the plane of the coupled panels and in a horizontal direction in this plane and perpendicular to the respective edge. The wood veneer and/or the substrate immediately underneath the wood veneer is treated at least at the short edges with a fluoro copolymer or a polymeric methylene diphenyl diisocyanate.

A set of mutually lockable panels comprises a first panel having an edge including a male part and a second panel having an edge including a female part for receiving the male part of the first panel in unlocked condition of the panels. The male part has an outer side which, in locked condition of the panels, is directed to the second panel in a direction substantially parallel to the front face of the first panel, and an opposite inner side which is provided with a locking surface. The female part comprises a locking member, which is pivotable about a pivot axis that extends substantially parallel to the edge of the second panel and an actuator for rotating the locking member from its unlocked condition to a locked condition of the panels.

A set of floor panels for forming a floor covering, which comprises at least two floor panels, which each comprise an edge provided with a coupling part, wherein the coupling parts are configured such that they allow realizing a coupled condition between the floor panels, by means of a substantially straight-lined coupling movement of the one floor panel in respect to the other floor panel, according to a direction substantially perpendicular to an installation plane; and wherein the coupling parts are configured such that they, in the coupled condition, realize a tensioning force pressing the coupled edges towards each other.
